COAL HOISTlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 313,880, dated March 17, 1885.

Application filed July 10, 1884. (No media.

To aZZ whom it may concern.-

Be it known that I, DEWITT O. NIBLIoK, a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improve V ment in Goal-Hoisting Apparatus, of which the following is a specification.

My invention consists in an improved apparatus for hoisting and unloading coal from vessels, &c.

In this invention the mast is hinged or swiveled to the platform or frame-work of the dock or landing, and itis provided with averticallymoving slide, to which the boom is hinged. The boom is furnished with a vertically-adjustable projecting arm or frame provided with a track carrying a movable car, upon which the bucketpulleys are mounted. This projecting frame is also furnished with a hopper having a hinged door, into which the coal from the bucket is emptied. When the bucket is elevated by its rope so that its bottom will clear the bottom ofthe hopper, the slide or car on which the bucket-pulleys are mounted moves inwardly on its track and carries the bucket into the hopper into position for dumping or unloading its contents. The hinged portion or door of the hopper is provided with a lever operated by the sliding pulley-carriage to lift or close the door as the bucket moves into the hopper, thus extending or continuing the chute or bottom of the hopper to prevent any spilling of the coal. The bucket has a hinged side or door provided with a catch engaging with a latch or trip-lever, which is operated or opened automatically by striking against a pin or stop as the bucket and its pulley-carriage is drawn into position over the hopper on the proj eetin g frame. An adjustable chute communicates from the hopper to the dump-car. This hopper is divided at its mouth into two delivery-chutes, the same having a hinged gate or divider, so that all the coal may be directed into one or the other mouth, as desired, so that however the mast is turned on its axis the chute will operate to deliver the coal into the dump-car. Suitable guyropes are provided for turning and holding the mast into position, and suitable pulleys and lines for raising and inclining the boom, the projecting frame which carries the pulleycarriage, and also the chute.

The other features of the invention consist in the novel devices and novel combinations of devices herein shown and described.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, I have illustrated in Figure 1 a side elevation of an apparatus embodying my invention, and which I consider to be the best way now known to me of practicing the same. Fig. 2 is an enlarged detail view showing the bucket in side elevation in position for emptying, part of the hopper being broken away. Fig. 3 is a plan view of the chute. Fig. at is a vertical section ofthe movable slide to which the boom is hinged. Fig. 5 is a plan view of the movable carriage on which the bucket-pulleys are mounted, and Figs. 6 and 7 are detail views of the pulley and line-guard of the bucket.

In the drawings, A represents the platform or frame of the dock or landing, to which the mast B is hinged by the strap a and pivot a. The mast B is provided with projections or arms Z), to which the guy-lines b are secured for holding the same in position.

G is the vertically-moving slide on the mast, to which the boom D is pivoted by the hinge d. This slide G is adjusted up and down upon the mast by means of the rope or line 0 and pulleys c c", the end of the line being belayed to the cleat c on the mast. The boom D is inclined on its pivot and supported by the line (1, which is fastened at its extremity to the end of the boom, and passes around a pulley on the double block d thence around the pulley d secured to the boom, and thence back over the second pulley on the double block d to the cleat on the mast, to which it is secured.

E represents an adjustable frame or arm projecting from the boom and hinged or secured thereto by the pin 0, passing through a slot or guideway, e, on the boom, and supported at its end by the line-c secured there to, which passes overthe pulley c on the boom, and thence over a pulley on the double block 6 secured to the mast, and having its eXtremity belayed to a suitable cleat 011 the must. The outward end of the frame E is adjusted and supported. by means of a line, 6 which is secured to the double block 6", and which passes over and around the double block e near the top of the boom, and thence over the pulley on the double block 6 on the mast to its belaying-cleat. The projecting arm or frame E should preferably stand at about a right angle to the boom, and it is provided with a track, F, on which is mounted the pulley carrying car G. The rollers g of this car or slide move up and down on the track.

H is the hoistingbucket. Its line h is secured at one extremity to the pulley-carriage G, and thence passes around the pulley h on the bail 7Z2 of the bucket, and thence over the pulley k on the car G, and thence over the pulleys li and Won the boom, and down through the pulley h on the mast to the winding-drum or source of power. The bucket H has a hinged door or side, I, provided with a lookingcatch, 2', one on each side, in which engages the notched bent lever t, which is made double, or provided with a locking-notch on each side of the bucket, and the top of which extends over the top of the bucket like a bail, but projects or inclines slightly forward of the bail. The pivoted locking-lever t" is provided with a spring, i, to hold the same in position for locking the door shut. The door may be very conveniently closed by the workman touching it with his shovel as the bucket descends into the hold of the ship. Generally, however, the hinged door will close itself when the bucket strikes the bottom. WVhen the bucket is hoisted up so that its bail projects against the bottom of the car G, the further drawing in of the line h causes the pulleycarriage G to be drawn up on the track F and into or over the hopperK, which is secured, preferably rigidly, to the frame E. When the bucket is thus drawn into position for discharging its contents into the hopper by the inward movement of its pulley-carriage G, the tripping-lever 2' strikes against a projecting stop, pin, or bar, J, secured to the hopper or to the frame E, thus causing the latch or lever i to turn on its pivot i and release or unlatch the hinged side or door I, and thus discharge the contents of the bucket into the hopper automatically. The hopper K is provided with a hinged extension or door, K, and at the same time that the pulley-carriage Gis drawn up on its track by the hoisting-line this hinged extension K is closed or raised into the position shown in Fig. 2 by'means of a bent lever, 70, pivoted by the pin is to the hopper, one arm, k of which is provided with aslot, kiengaging with a pin, lc*,on the door K, and the other bent arm, of which is provided with a slot, 7c, in which fits a pin or bolt, 75, on the carriage G, so that the movement of the carriage up or down on its track will raise orlower this hinged extension. One of these bent levers, 7c, should be provided on each side of the hopper. The pulley h on the hail of the bucket is provided with a hinged line-guard, h h, one for each branch of the line, which serves to hold the pulley in an upright position and prevent the hook from turning wrong side up when the bucket is disengaged from its hook H. This line-guard being hinged to the pulley-axis permits the same to open out, as shown in Fig. 6 or in Fig. 7 in dotted lines, and thus assume the direction of the line when the same changes by reason of the bucket being drawn up against its carriage. The hinged line-guard thus prevents any cutting or unnecessary friction upon the line. The chute L rests loosely upon a cross beam or arm, I, secured to the mast, and is adjusted and supported at its outer end by means of a line, Z, secured thereto, which passes over a pulley, Z", on the hopper, and is thence fastened to a cleat, P, on the boom. The chute L is furnished wit-h two discharging-mouths, L L, which fit astride the mast, and ,L isagate or divider, hinged at L, and which may be turned by means of a rope, L passing through eyes L in the chute, so as to permit the coal to be discharged from both mouths at once or shut entirely off from one or the other, as may be desired.

By means of my invention it will thus be seen that the mast and boom can be readily adjusted so as to reach either hatch of almost any vessel, as the mast can be turned or swiv'- eled on its axis, and the boom elevated on its slide or inclined to the mast, as the exigencies of the case may require.
